The method includes encoding first signaling information for a physical layer to generate a first coded block; encoding second signaling information to generate a second coded block; and transmitting a frame including the first coded block, the second coded block, and at least one physical layer pipe (PLP) data. The first signaling information has a fixed number of bits, and the second signaling information has a variable number of bits. The first signaling information includes information indicating a forward error correction (FEC) type of the second signaling information for receiving the second information, and the second signaling information includes information indicating a modulation scheme used for a related PLP data.
